SIDING=GAGE.

. SPECIFICATION forming part of Letters Patent. No. 390,459, dated @ctooer 2, 1888.

Application filed October I, 1887.

To aZZ whom it may concern:

Be it known that 1, AUGUSTUS O. L. DAVIS, of Madison, in the county of Madison and State of Nebraska, have invented a certain new and useful Improvement in Siding Gages or Dogs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure I is a perspective view of myimproved gage. Fig. II is a side View showing the gage in working position and weatherboards or siding in section. Fig. III is a transverse section taken on line III III, Fig. II.

Referring to the drawings, 1 represents guide-rods, and 2a double hook-shaped spring." 3 representsa dog, which works on the guiderods 1; 4, the knob on the dog, and 5 the metal point on the dog. The dog is composed of two plates, 6 and 7, each having two grooves on its inner surface. The guide-rods slide in these grooves and through holes in the lower end of the plate 6, (which is at right angles to the plate.) The two plates are secured together by means of the screw-knob 4-, which is also a handle for pressing the point into the siding and for withdrawing the same.

8 is a horizontal bar above the guide-rods 1, having a vertical part, 9, into which the guiderods are secured, and a vertical part, 10, into which the downwardly-extending ends orlegs of the spring 2 lit. A metal point, 11, is at tached to the upper side of the horizontal bar 8 and a knob, 12, to the outside of the vertical part 10.

The operation of my device is fully shown in Fig. II, where the siding or weather-boards are shown in section. When a siding or weatherboard is put in place, the metal point 5 is pressed into the second board beneath and the point 11 into the board last secured in place, and the next board is placed on the said point, and by this means the boards are kept l at an equal distance apart. The spring 2 presses against the board to be secured and holds it in the desired position until it is nailed in place. The spring may be withdrawn and turned in the other direction in cases of very thick boards, as shown by dotted lines, Fig. II.

By my siding-dog arrangement it will be seen that a change to another size may be very quickly and easily made.

The springs 2, having broad bearings, hold the board against which they bear very securely.

I claim as my invention 1. The combination, with a gage having a horizontal portion, 8, downwardlyextended portion 9 at one end of thelatter, and upwardlyextended portion 10 at the other end provided with vertical holes, of the U-shaped spring bent back on itself from the top and having legs adapted to be inserted in said holes, whereby the spring can be reversed to accommodate boards of different thicknesses, substantially as set forth.

2. In a gage, the combination of the guiderods and a sliding dog consisting of an angularly-bent plate provided with holes through which said rods pass, the vertical portion of said plate engaging said rods on one side, a plate on the opposite side, a screw-knob for securing the plates together against the rods, and a prong secured to the horizontal portion of the angular plate, substantially as set forth.

3. In a gage, the combination of the rods, pointed dog on the rods, horizontal bar 8, having vertical portions 9 and 10 at each end, said rods being secured in portion 9, a spring secured in portion 10, and knobs 4 and 12, substantially as and for the purpose set forth.

AUGUSTUS C. L. DAVIS.
